Octopus analog rotation brick is a 10K potentiometer module. Rotating the knob to change its resistance can realize voltage division while providing analog signals to the analog input IO ports of micro-controller. This module has a 3-wire anti-reverse connector, which makes it easy to connect a GVS cable.
Features
Integrate a 3-wire anti-reverse connector.
Rotate the knob to adjust resistance without using a screw driver.
Compact structure.

Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
